Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed June 20, 1907. flerisl l lo. 879,985.

To'all whornt't may concern:

Be itklnown that I, JOHN S. BAYER, a citizen of the United States, residing zit-Warren, in the county of Warren and State of Pennsylvania, have invented cerwhich. will overcome the weakness in the joints or couplings now used.

Myinvention relates to certain other novel features of construction which will be hereinafter described and pointed out in the claims.

In the accompanying drawing-Figure l is a view in side elevationoi one of the sections. Fig. 2 is asectional view showing the jointing or'coupling of two sections. Fig. 3 is a sectional view showing the two sections coupled together. I

A, represents one of the sections of the culvert, which is preferably made corrugated and of galvanized or other suitable iron. The section is made in any shape desired, but I have shown itmade round, and riveted together horizontally as at 2.

One end of the section has a raised collar or hell 3,

and the end 4 ofthe section is received within the joint or coupling is formed. This coupling makes a stronger joint, and the advantage over the couplings now in use, is that they are weak. as thc ends (:5 a section being the weaker part. but. by having one cur made in the shape of a bell and having the end of the section to be joined inserted within i'hc bore of the conform to the bell, and having the hell or collar bent down over the corrugation, which can be done with a hammer, or with any suitable means, and by making the couplings in this manner and the fact that it is reinforced by the rings or corrugations at the joints makes it strong, and will not break or become weakened. In some ases it may be desirable to fill in the space between the corrugation and the rim of the bell.

,made in the form and arrangement. of the several parts described without departing from the spirit and scope of tny'invention, and hence I do not wish to limit myself to the exact construction herein set forth, butz-- Having fully described my invention, What I claim as new and desire to secure by Letters Patent. is:-

In culvert, the combination of a plurality of corrugnted sections. said sections having an open hell at one end adapted to receive the end of the adjoining section. the ring or corrugation on the section received within lhc bell. and the rim of the bell bent down around the ring or corrugation.

In testimony whereof I have signed m v name to this specification in the presence of two subscribing witnesses.
